In California, child support is also based on the state's guideline calculations. The biggest factors in those calculations are: (1) The amount of income the mother earns, (2) The amount of income the father earns, and (3) The amount of time you each spend with your daughter.
Given that your daughter spends most of her time with you, and that the father is working and you are not, he will almost certainly have to pay you child support.
However, because you are going to school and not looking for work, he can try to argue that you should be "imputed" with income (this means that the court pretends that you are making a certain amount of money since you should be able to earn that amount if you were actually looking for work). This is a difficult argument for him to win on though, especially if you are close to finishing your degree. You can argue that it makes a lot more sense for you to complete your degree so that you have a higher long-term earning potential, which in the long-run, will make the child support amount go down, since you will be more able to support your daughter with your own earnings.
I'm a CT attorney, and not a CA attorney, and I'm sure the CA attorneys will weigh in. However, in my state there are child support guidelines which the judge is required to follow unless there is "deviation criteria" present in the case. As to his subverting your claim by his failure to work "over" the table, in my state, an order can be based on someone's earning *capacity* instead of their earnings, if they are willfully underemployed or otherwise attempting to avoid responsibility. Good luck.
